35. RS 1
The cam mounted to the main shaft of the flat spring motor turns in a counterclockwise direction.

36. RS 2
The force of the cam’s rotation against the leg armature causes the main coil spring to be stretched (storing energy) and the torso of the mouse to be pushed downward and forward.

37. RS 3
When the rotating cam reaches its point of disengagement with the leg armature, the energy stored in the main coil spring is released causing the
torso of the mouse to be jettisoned backwards and upwards momentarily overcoming the effects of gravity.

38. RS 4
The backward and upward inertia that the main coil spring imparts to the torso causes the mouse to rotate around its own center of gravity.

39. RS 5

40. RS 6
Note. The energy stored and released from the main coil spring has been adjusted to impart the proper amount of inertia to allow the mouse to land back on its feet.
